GENTRIFUGAL MACHINE.

Specification of Letters Patent.-

Patented Mar. 23, 1915.

Application filed May 1c, 1913. Serial, mf 788,002.

To all whom it may concern.-

Be it known that I, WILLIAM L. DOLInn, residing in the city ofPhiladelphia and State of Pennsylvania, have invented certain new anduseful Improvements in Centrifugal Machines, of which the following is aspecification.

My invention relates to centrifugal .machines for the extraction ofliquids from solids, fabricsor fibrous material, and for similar uses.

My invention resides in apparatus of the character above referred to inwhich the centrifugal drum or basket is rotated by a steam turbine orimpulse wheel so associated with the basket that the steam or motivefluid after impact u'on the motor blades or buckets passes directly intothe basket. And it is afurther feature of my invention that,particularly for machines of small size, the motor blades or buckets areformed in parts formed on or struck out from the basket withcomplementary parts formed on or struck out from the bottom member ofthe bowl or basket.

My invention resides in the features here; inafter described andclaimed. 1

For an illustration of one of the many forms my invention may takereference is to be had to-the accompanying drawing, in which:

Figure 1 is a vertical sectional view, arts in elevation through amachine embo ying my invention. Fig. 2is a fragmentary horizontalsectional view illustrative of the structure shown in Fig. 1.

The centrifugal bowl, drum or basket B, walls perforated and having Ihaving its side the top inwardly extending flange F is secured at itslower margin b rivets r to the upturned flange f of the ate or disk Dwhich may be the bottom u the basket B.

The disk or plate D, and therefore the bowl or drum B, is secured to theshaft S by nut N screw threaded on the upper end of the shaft 5 andpressing together the collars a and 1) between which the bottom D isclamped, the collar B thrusting against the shoulder on the upper end ofthe shaft S. A ball or other suitable bearing C is provided, the shaftS' having also bearings E and G in the member H secured to or integralwith the bottom I of the casing J which incloses the centrifugal basketB. The cas ing J is cast integral with or otherwise supported by thepedestal P.

is an oil cup or reservoir from. which oil is fed through pipe Pinto thecavity or chamber 0 in member H, the chamber a being closed at itsbottom by the screw threaded plug d. Oil rises through chamber a,bearing G, chamber e, bearing E, into chamber 9 maintaining the bearing0 flooded with oil.

From the lower margin of the basket or drum B are cut or punched, asalong three sides of a parallelogramor rectangle, the blade or vanemembers 0 which are then bent inwardly as shown in Fig. 2. Similarlyblade or vane members o are formed upon or attached to upturned flange fof the bottom or plate D, as shown in Fig. 2, vane members '1). and vbeing complementary to each other to 'makecomplete vanes,

blades or buckets of a rotor of aturbine or motor, the spaces oropenings in the members Band f from which the vanes are bent out formingpassages for the steam or other motive fluid, as shown in Fig. 2. Them0- tive fluid is supplied through the nozzle L extending through theside wall of easing J in a direction to deliver steam into the bucketsor vanes as indicated.

The operation is as follows: Oily waste or any other material to betreated or op erated upon is placed inside of the drum or basket B andthe cover K replaced into position'shown. Steam is then delivered to thenozzle L from any suitable source, as a steam boiler, and steam strikesthe vanes or buckets as indicated causing rotation of the basket B athigh speed, whereupon, due to centrifugal action, liquid is separatedfrom the contents of the basket B. It will .be

noted that the steam strikes upon the vanes or buckets and passes fromtheir inner parts 4) directly into the basket B through the false bottomM, which may be a perforated metal plate, or may be a sheet of wiregauze. This steam escaping directly into the basket assists inseparating the oil, for example,

from the waste, due to the heating effect, and possibly other effects.The steam which does not condense in its' passage through the basketafter leaving the motor escapes into the casing J and thence outwardlythrough the exhaust pipe X. The water of condensation and the oil orother liquid sepa rated from the contents of the basket collect in thebottom of the casing J and pass into the trap T'whose upper orificecommunicates with the interior of the casing J. The liquid materialflows into the trap T and downwardly around the web or diaphragm U andthence out through the aperture V to any suitable tank or othercollector.

It is to be understood that other structures than the one illustratedmay be used whereby the steam passes directly from the motor vanes orbuckets into the interior of the basket B. Thus, for example, for largermachines, where greater efficiency of the motor is desired, the bladesor vanes may be of proper curved shape and cast integral upon a membersimilar to the bottom D at the outer margin thereof, and the basket ordrum disposed upon the upper edges of such blades or buckets, and inthis case also steam escaping from the buckets or vanes passes directlyupwardly into the basket B.

What I claim is: p

1. The combination with a centrifugal basket, of a bottom therefor towhich said basket extends, said basket having perforations at saidbottom, motor buckets or vanes disposed at said perforations above saidbot tom, and a false bottom within said basket disposed above said vanesor buckets.

2. The combination with a centrifugal basket, of a bottom therefor towhich said basket extends, said basket having perforations at saidbottom, motor buckets or vanes disposed at said perforationsabove saidbottom, a false bottom within said basket disposed above said vanes orbuckets, and means for delivering motive fluid to said vanes or bucketsto drive said basket, said motive fluid after impact upon said vanes orbuckets passing upwardly into said basket through said false bottom.

. 3, The combination with a centrifugal basket, of a bottom therefor,motor vane or bucket members struck out from said basket,

an upturned flange secured. to said bottom, a

basket, of a bottom therefor, a flange on said bottom, said flange andsaid basket having registering openings, and motor vanes or bucketsdisposed at said openings.

5. The combination with a centrifugal basket, of a bottom therefor,aflange on sai l bottom, said flange and said basket having registeringopenings, motor vanes or bucket members disposed at said openings, apart of each vane or bucket carried by said basket, and a complementarypart of each vane or bucket carried by said flange.

6. The combination with a centrifugal basket, of a member securedthereto, motor vane or bucket members, a part of each vane or bucketmember extending in one direction from said basket, and a complementarypart of each vane or bucket member extending in another direction fromsaid first named member.

7. The combination with a centrifugal basket, of separate bottomstherefor, motor vane or bucket members disposed between said bottoms, arotary shaft supporting said basket, and bearings for said shaftdisposed beneath said basket and said bottoms.

In testimony whereof l have hereunto affixed my signature in thepresence of the two subscribing witnesses.
